What is a quality control product? quality control product noun
At present, domestic quality control products (quality control serum),standardThe concepts of calibration products (calibration serum), reference products (reference materials), and reference materials are very confusing. Everyone has their own name, and everyone has their own understanding. Personally, I believe that the meanings of these nouns are similar. Translated into English, it is better to understand. Now I would like to express my personal opinions on these five most common nouns.
First of all, the most commonly used terms are quality control (Control) and standard (Standard). Among them, the concept of quality control is clearer and can be used for quality control. Only individual quality control products composed of serum matrix are also called quality control serum, and the overall concept is clear. The concept of standard is widely used in most fields, such as length, weight, current, light intensity, and quantity of substances.
However, due to the existence of the matrix effect, the application of standards in medical and biological testing has a certain narrowness. If the standard pure FeCl3 reagent is accurately weighed by the weighing method and prepared into a standard aqueous solution, it is provided by the National Standard Network. It is used as a calibration liquid calibration detection system to detect human blood samples, which is often quite different from the true value.
Therefore, there was later research on calibrators, which were generally serum substrates, also known as calibration sera. Some items were aqueous solutions, and the marked value of the calibrator was often different from its true content. The characteristic was that it could only be used to calibrate the detection system, and it was used for the calibration of other systems, often without satisfactory results.
For example, Roche and Randox, the two largest quality control manufacturers in the world, the GGT items in the two calibrators claim to be traced back to the international standard substance CRM? IRMM? IFCC? 452? γ-glutamyltransferase (GGT). When calibrating the Roche instrument with Roche calibrators, the test samples can get accurate values. When used to calibrate the Randox system, it often deviates from the true value. And vice versa
